[0045] Reference Figures 1 to 10 The following are several embodiments of the lifting and guiding mechanism of the quick-freezing machine of this utility model and the quick-freezing machine itself.

[0046] like Figures 1 to 2 As shown, the lifting guide mechanism of the quick-freezing machine according to this embodiment of the present invention includes a guide member 100 and a rolling assembly 200. The guide member 100 includes two guide surfaces 111 arranged opposite to each other, and the guide surfaces 111 extend along the height direction of the quick-freezing machine. The rolling assembly 200 includes a connector 210 and two rolling members 220 disposed on the connector 210. The connector 210 is used to connect the cold plate 400. The guide member 100 is located between the two rolling members 220. One rolling member 220 rolls on one of the guide surfaces 111, and the other rolling member 220 rolls on the other guide surface 111, so as to guide the rolling assembly 200 to move along the height direction of the quick-freezing machine.

[0047] The two guide surfaces 111 of the guide member 100 are arranged opposite to each other. The guide member 100 is located between the two rolling members 220. During the lifting and lowering of the cold plate 400, it is subjected to the traction force of the cold plate 400. One of the rolling members 220 rolls on one of the guide surfaces 111, and the other rolling member 220 rolls on the other guide surface 111. Since the guide surface 111 extends along the height direction of the blast freezer, the two rolling members 220 move along the height direction of the blast freezer, thereby guiding the cold plate 400 to move along the height direction of the blast freezer, reducing the risk of the cold plate 400 tilting or swaying during the lifting and lowering process, and improving the stability of the lifting and lowering of the cold plate 400.

[0048] like Figures 1 to 2 As shown, the guide member 100 is located between the two rolling members 220, so that the rolling members 220 can abut against the corresponding guide surface 111, and thus the rolling members 220 can roll on the corresponding guide surface 111 under the traction force of the cold plate 400; the two guide surfaces 111 of the guide member 100 are arranged opposite to each other, and the two rolling members 220 are connected to the same connector 210, so that the two rolling members 220 move synchronously, thereby improving the stability of the rolling assembly 200.

[0049] The guide surface 111 extends along the height direction of the blast freezer, and one of the rolling elements 220 rolls on one of the guide surfaces 111. Through the cooperation of the guide element 100 and the two rolling elements 220, the rolling assembly 200 can be guided to move along the height direction of the blast freezer, thereby guiding the movement direction of the cold plate 400. The rolling wheel 222 rolls on the guide surface 111. The contact surface between the rolling wheel 222 and the guide surface 111 is a point or line contact, with low friction, significantly reducing wear and thus extending the service life of the lifting guide mechanism. Due to the cooperation characteristics of the rolling wheel 222 and the guide surface, energy loss can be minimized and the stability of the movement of the rolling assembly 200 can be improved.

[0050] In some embodiments, such as Figures 1 to 2 As shown, the length of the connector 210 is greater than two-thirds of the width of the cold plate 400 in the length direction of the connector 210. By increasing the length of the connector 210, the contact area between the connector 210 and the cold plate 400 can be increased, the reliability of the connection between the connector 210 and the cold plate 400 can be improved, and the movement direction of the cold plate 400 can be better guided.

[0051] In some embodiments, such as Figures 2 to 3As shown, the rolling element 220 includes a support shaft 221 and a rolling wheel 222 rotatably connected to the support shaft 221; the rolling assembly 200 also includes an adjuster 230, which includes a fixed seat 231 and an elastic element 232. The fixed seat 231 is disposed on the connector 210, and the fixed seat 231 is provided with a mounting groove 231a for the elastic element 232; the elastic element 232 is connected to the support shaft 221, and the elastic element 232 provides an elastic force to the support shaft 221 so that the rolling wheel 222 abuts against the corresponding guide surface 111.

[0052] The elastic force of the elastic element 232 ensures that the rolling wheel 222 abuts against the corresponding guide surface 111, maintaining contact between the rolling wheel 222 and the guide surface 111. This ensures that the guide surface 111 guides the movement of the rolling assembly 200, preventing the rolling assembly 200 from detaching from the guide surface 111 during movement and affecting the guiding effect. The elasticity of the elastic element 232 also ensures that the rolling wheel 222 remains in contact with the guide surface 111 even when the cold plate 400 is tilted or swaying, allowing the rolling assembly 200 to maintain linear movement and thus limiting the direction of movement of the cold plate 400.

[0053] like Figures 3 to 4 As shown, generally, the elastic element 232 is a spring; the elastic element 232 can be arranged along the direction from one guide surface 111 to the other guide surface 111 so that the elastic element 232 provides an elastic force to the support shaft 221; one adjuster 230 can be provided, and the support shaft 221 of one of the rolling elements 220 of the rolling assembly 200 is connected to the elastic element 232, and the support shaft 221 of the other rolling element 220 is connected to the connector 210.

[0054] For example, such as Figures 3 to 5As shown, the two rolling elements 220 are the first rolling element 224 and the second rolling element 225, and the two guide surfaces 111 are the first guide surface 130 and the second guide surface 140, respectively. The first rolling element 224 rolls on the first guide surface 130, and the second rolling element 225 rolls on the second guide surface 140. The elastic element 232 of the adjuster 230 is connected to the support shaft 221 of the first rolling element 224. The elastic force of the elastic element 232 causes the rolling wheel 222 of the first rolling element 224 to abut against the first guide surface 130. Since the guide element 100 is located between the two rolling elements 220, and the two rolling elements 220 are connected to the same connecting element, the rolling element 224 is abutting against the first guide surface 130. If, due to shaking or tilting during movement, the second rolling element 225 fails to abut against the second guide surface 140, resulting in a gap between the second rolling element 225 and the second guide surface 140, the elastic element 232 of the adjuster 230 releases its elastic force, causing the rolling assembly 200 to move along the direction from the second rolling element 225 to the first rolling element 224. The second rolling element 225 moves towards the first rolling element 224 until it abuts against the second guide surface 140. Only one adjuster 230 is needed to ensure that both the first rolling element 224 and the second rolling element 225 abut against their respective guide surfaces 111. In other embodiments, two adjusters 230 can be provided, with the elastic element 232 of one adjuster 230 connected to the support shaft 221 of the first rolling element 224, and the elastic element 232 of the other adjuster 230 connected to the support shaft 221 of the second rolling element 225. This embodiment of the present invention does not impose any particular limitation on this.

[0055] like Figures 3 to 5As shown, the fixed base 231 is provided with a mounting groove 231a for the elastic element 232. The mounting groove 231a allows for quick determination of the installation position of the elastic element 232, facilitating its installation. The elastic element 232 is at least partially located within the mounting groove 231a, which extends along a direction from one guide surface 111 to the other. The mounting groove 231a provides a certain guiding effect for the extension and retraction of the elastic element 232. The elastic element 232 is sleeved on the outside of the support shaft 221, wherein the support shaft 221 of the first rolling element 224... 1. The first rolling element 224 is arranged along the direction from one guide surface 111 to the other guide surface 111. The support shaft 221 can effectively guide the elastic element 232 to extend or contract along the direction from one guide surface 111 to the other guide surface 111. The first rolling element 224 also includes a connecting shaft 223, and the rolling wheel 222 is fixed to the end of the connecting shaft 223. One end of the support shaft 221 is provided in the mounting groove 231a, and the other end is provided with a rotating hole 221a. The connecting shaft 223 passes through the rotating hole 221a, so that the rolling wheel 222 is rotatably connected to the support shaft 221. The rolling wheel 222 of the second rolling element 225 is directly rotatably connected to the support shaft 221 of the second rolling element 225, and the end of the support shaft 221 of the second rolling element 225 is fixed to the connecting element 210.

[0056] In some embodiments, such as Figure 5 As shown, at least two rolling components 200 are provided, and the at least two rolling components 200 are arranged at intervals along the height direction of the quick-freezing machine. Through multiple rolling components 200, the movement direction of multiple cold plates 400 of the quick-freezing machine can be guided, improving the stability of the cold plates 400 during the lifting process, thereby ensuring the normal operation of the quick-freezing machine. The lifting guide mechanism also includes a support frame 300, which is connected to the connector 210 of two adjacent rolling components 200, and the support frame 300 provides support for the rolling components 200.

[0057] It should be noted that the first rolling elements 224 of the multiple rolling components 200 are arranged at intervals along the height direction of the blast freezer, so that the first rolling elements 224 of the multiple rolling components 200 can cooperate with the same guide surface 111 to ensure that the movement direction of the multiple cold plates 400 is consistent; similarly, the second rolling elements 225 of the multiple rolling components 200 are arranged at intervals along the height direction of the blast freezer.

[0058] In some embodiments, such as Figures 5 to 6As shown, the connector 210 is provided with a sliding groove 212, which extends along one guide surface 111 to the other guide surface 111; the support frame 300 includes two cross-arranged support arms 310, which are rotatably connected; one support arm 310 is rotatably connected to one of the adjacent connectors 210, and the other support arm 310 is slidably disposed in the sliding groove 212 of the other connector 210.

[0059] It is understandable that during the lifting and lowering of the cold plate 400, adjacent cold plates 400 move away from or closer to each other, and the support arms 310 rotate relative to each other, with both support arms 310 sliding within their corresponding sliding grooves 212. Since the sliding grooves 212 extend along the direction from one guide surface 111 to the other, the relative rotation of the two support arms 310 increases or decreases the distance between the two rolling components 200 to accommodate different spacings between the cold plates 400. Simultaneously, the two support arms 310 are arranged crosswise, distributing the load between them, which reduces the stress on a single support arm 310. Both support arms 310 provide support for the rolling components 200 and improve the overall stability of the lifting guide mechanism. Because plasma bags have various thicknesses, the distance between adjacent cold plates 400 needs to be adjusted according to the thickness of the plasma bag. This embodiment of the invention, through the relative rotation between the two support arms 310, satisfies the support effect for the cold plates 400 while adapting to different spacings between them, demonstrating high adaptability.

[0060] In other embodiments, the support frame 300 can also be a guide rod with a groove provided on it. The groove is provided along the length of the guide rod, and a slider can be provided on the connector 210. The sliders of two adjacent rolling components 200 are slidably disposed in the groove. The guide rod is provided along the height of the quick-freezing machine, and the movement direction of the rolling components 200 can be further guided by the guide rod.

[0061] In some embodiments, such as Figures 5 to 6 As shown, two support frames 300 can be provided between two adjacent rolling components 200. The two support frames 300 are arranged along the direction from one guide surface 111 to the other guide surface 111. The two support frames 300 can increase the support area of ​​the two adjacent rolling components 200, and further ensure the stable movement of the rolling components 200.

[0062] In some embodiments, such as Figures 5 to 7As shown, the guide member 100 is provided with at least two limiting steps 120, which are arranged at intervals along the height direction of the guide member 100. The at least two limiting steps 120 correspond one-to-one with at least two rolling components 200. The rolling component 200 also includes a limiting member 240, which can abut against the corresponding limiting step 120.

[0063] It is understandable that by having the limiting member 240 abut against the corresponding limiting step 120, the movement range of the rolling assembly 200 can be limited, preventing the rolling assembly 200 from exceeding the preset stroke. Generally, the topmost cold plate 400 is fixedly installed, and the distance between two adjacent cold plates 400 is changed by controlling the rise or fall of the bottommost cold plate 400. At least two limiting steps 120 are arranged at intervals along the height direction of the guide member 100. When the cold plate 400 falls to its maximum stroke, the limiting member 240 of the rolling assembly 200 corresponding to different cold plates 400 abuts against the corresponding limiting step 120. It should be noted that since the topmost cold plate 400 is fixedly installed, there is no need to install the limiting member 240 on the topmost rolling assembly 200. Similarly, there is no need to install the limiting step 120 corresponding to the topmost rolling assembly 200 on the guide member 100. At least two limiting steps 120 are arranged at intervals along the height direction of the guide member 100 to facilitate the processing of the guide member 100. Generally, the limiting member 240 is a block fixed on the connecting member 210; along the height direction of the quick-freezing machine, the height of both the limiting member 240 and the connecting member 210 is less than the thickness of the cold plate 400, so as to avoid the limiting member 240 or the connecting member 210 from hindering the movement of the cold plate 400; in other embodiments, the limiting member 240 may be a column or a ball or other shapes, and this utility model embodiment does not limit this.

[0064] In some embodiments, such as Figures 5 to 7 As shown, the guide member 100 includes two guide portions 110 arranged side by side. Each guide portion 110 has a guide side 112 and a limiting side 113, which are opposite to each other. A guide surface 111 is provided on the guide side 112, and a limiting step 120 is provided on the limiting side 113.

[0065] It is understandable that the guide side 112 and the limiting side 113 are opposite to each other. The guide surface 111 is set on the guide side 112, which simplifies the structure of the guide part 110 and facilitates the processing of the guide part 110. The limiting step 120 is set on the limiting side 113. That is to say, the rolling wheel 222 rolls on the guide side 112, and the limiting member 240 abuts against the limiting side 113. The limiting member 240 and the rolling wheel 222 correspond one-to-one. Generally, the guide part 110 is strip-shaped, which can shorten the distance between the guide side 112 and the limiting side 113 to the greatest extent, that is, shorten the distance between the rolling wheel 222 and the limiting member 240. When the cold plate 400 descends to the maximum stroke, the limiting member 240 abuts against the limiting side 113, which can stop the corresponding rolling wheel 222 from continuing to roll in time, improving the flexibility of the lifting guide mechanism.

[0066] In some embodiments, such as Figure 5 As shown, the guide member 100 includes two guide portions 110 arranged side by side, with a guide surface 111 located on the side of the guide portion 110 facing away from the other guide portion 110, in order to maximize the distance between the two guide surfaces 111, thereby ensuring the uniformity of the supporting force of the rolling assembly 200 on the cold plate 400, and thus enabling the cold plate 400 to move stably; the support frame 300 is located between the two guide portions 110, ensuring that the distance between the two guide surfaces 111 is large enough, while increasing the supporting force on the cold plate 400, and can make full use of the space between the two guide surfaces 111, making the overall structure of the lifting guide mechanism more compact.

[0067] In some embodiments, such as Figure 6 As shown, the rolling assembly 200 also includes a heat insulation element 250, which is disposed on the side of the connector 210 near the cold plate 400 to isolate the connector 210 and the cold plate 400, thereby limiting heat transfer between them. The heat insulation element 250 is made of a non-metallic material, which typically has low thermal conductivity, thus limiting heat transfer between the connector 210 and the cold plate 400. For example, the heat insulation element 250 can be made of plastic, ceramic, or other materials. Generally, the heat insulation element 250 is sheet-shaped, which, while providing heat insulation, reduces the space occupied by the heat insulation element 250, thereby reducing the overall volume of the rolling assembly 200.

[0068] In some embodiments, such as Figures 7 to 8As shown, the connecting member 210 has an auxiliary wheel 211 on the side facing the guide member 100. When the rolling assembly 200 moves relative to the guide member 100 along the height direction of the quick-freezing machine, the auxiliary wheel 211 rolls on the guide member 100. The auxiliary wheel 211 can reduce the friction between the guide member 100 and the connecting member 210, making the movement of the rolling assembly 200 smoother. A fixing groove can be opened on the connecting member 210, and part of the auxiliary wheel 211 is located in the fixing groove. Both ends of the auxiliary wheel 211 are rotatably connected to the inner wall of the fixing groove.

[0069] A quick-freezing machine is provided in the second aspect of this utility model, such as... Figure 9 As shown, the quick-freezing machine includes a frame 500, a cold plate 400, a drive mechanism 600, and a lifting guide mechanism according to the first aspect embodiment above. The cold plate 400 is slidably disposed on the frame 500, and the guide member 100 is fixed to the frame 500. The connecting member 210 is connected to the cold plate 400, and the drive mechanism 600 is used to drive the cold plate 400 to rise or fall.

[0070] It is understood that since the lifting and guiding mechanism of the quick-freezing machine has the beneficial effects of the above embodiments, the quick-freezing machine will have the beneficial effects of the above embodiments. The specific implementation method can be referred to the above embodiments, and this application will not repeat it.

[0071] In some embodiments, such as Figure 2 As shown, there are two lifting guide mechanisms. One lifting guide mechanism is located on the first side 420 of the cold plate 400, and the other lifting guide mechanism is located on the second side 430 of the cold plate 400. The first side 420 and the second side 430 are opposite to each other. Through the two lifting guide mechanisms, the movement direction of the cold plate 400 can be guided from the first side 420 and the second side 430 of the cold plate 400, further reducing the risk of the cold plate 400 tilting or swaying during movement.

[0072] In some embodiments, such as Figure 2As shown, the quick-freezing machine also includes a guide shaft 710 and a buffer spring 720. The guide shaft 710 is mounted on the frame 500 and is arranged along the height direction of the quick-freezing machine. The cold plate 400 is provided with an opening 410 for the guide shaft 710 to pass through. The buffer spring 720 is sleeved on the guide shaft 710. The cold plate 400 is slidably arranged on the frame 500 through the guide shaft 710. The buffer spring 720 is located between two adjacent cold plates 400 and is in a compressed state. The buffer spring 720 is in a compressed state, meaning that its length in the relaxed state is greater than the maximum distance between two adjacent cold plates 400. The elastic force of the buffer spring 720 supports the two adjacent cold plates 400, improving the stability of their movement. The buffer spring 720 can be a rectangular spring, made of a material with a square cross-section. Compared to ordinary circular springs, rectangular springs have better resistance to deformation and breakage. Furthermore, compared to ordinary circular springs, rectangular springs have a smaller compressed volume for the same length, preventing the adjacent cold plates 400 from not being in close contact with the blood bag due to excessive compression, thus reducing the freezing effect of the blood bag. Of course, in other embodiments, the buffer spring 720 can also be an ordinary circular spring; this embodiment of the present invention does not impose any particular limitation on this.

[0073] In some embodiments, such as Figure 2 and Figure 9 As shown, the quick-freezing machine also includes a drive assembly. Multiple cold plates 400 are arranged along the lifting direction of the cold plates 400. The drive assembly drives the cold plate 400 at the bottom to move. The bottom cold plate 400 squeezes the other cold plates 400, thereby clamping and freezing the items located between two adjacent cold plates 400.

[0074] In some embodiments, such as Figures 9 to 10As shown, the drive assembly includes a base 610, a lead screw 620, a lead screw nut, a motor 630, and a scissor lift assembly 640. The scissor lift assembly 640 includes two cross-arranged support rods 641, which are rotatably connected. One end of one support rod 641 is fixed to the base 610, and the other end is slidably mounted on the bottommost cold plate 400. One end of the other support rod 641 is fixed to the bottommost cold plate 400, and the other end is equipped with a slider, which is slidably mounted on the base 610. The output shaft of the motor 630 is connected to one end of the lead screw 620, and the lead screw nut is sleeved on the outside of the lead screw 620 and connected to the slider. When the motor 630 operates, it drives the slider to slide on the base 610 through the lead screw 620 and the lead screw nut, thereby driving the two support rods 641 to rotate relative to each other, so that the bottommost cold plate 400 can rise and fall, improving the stability of the movement of the cold plate 400. Among them, the support rod 641 can be a curved rod to improve the strength and stiffness of the support rod 641, thereby improving the support force of the scissor lift assembly 640.

[0075] Through the above design, when the plasma bag needs to be quick-frozen, the drive assembly operates, pushing the bottommost cold plate 400 upward. The bottommost cold plate 400 pushes the other cold plates 400 upward, thereby clamping the plasma bag between two adjacent cold plates 400. Under the restoring force of the buffer spring 720, the squeezed plasma bag can be buffered to a certain extent, preventing the plasma bag from being squeezed and bursting. When the plasma bag needs to be removed, the drive assembly operates, pushing the bottommost cold plate 400 downward. The topmost cold plate 400 and the other cold plates 400 between the bottommost and topmost cold plates 400 begin to descend under their own gravity until all the cold plates 400 are completely separated, and the plasma bag can be removed.

[0076] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
